From time to time, I like to dip into C.S. Lewis's book
English Literature in the Sixteenth Century (Oxford History of English Literature). Here's what he says about Hugh Latimer, the greatest of the popular sort of preacher during the English Reformation. Hugh was an English priest who converted to protestantism in 1525, was made Bishop of Worcester in 1535, and burnt at the stake in 1555.
"...there is one man of real genius still to be considered. Hugh Latimer's character may be ambiguous or even repellent: his sermons, in their own kind, are resounding successes, 'though, to be sure, not very theological'. Latimer assents, indeed, to the doctrine of justification by faith, but he is no theologian; some of his apparent tergiversations may perhaps result from the bewilderment (even the impatience) of a 'plain man' entangled in matters above his capacity.
Whatever he may say (when he remembers) about faith, he is really so exclusively interested in works that not only a Papist but a Pelagian or even a good pagan could read nine-tenths of his sermons without a qualm. Nor is he a humanist: ego non calleo Graece, he professed in his final examination. He is one of the purest examples in English of the 'popular' preacher in the fullest -- if you will, the lowest -- sense of that word. He boasts himself the son of an English yeoman and works in 'the uprightly, plain Dunstable way'. He is full of anecdotes, jibes, digression, and simple vituperation; he takes his hearers into his confidence, explains how this or that illustration came into his head, forgets himself and recalls himself: all sounds as if it were extemporaneous.
We should probably be naive if we took the style at its face value. An appearance of casualness ('I am no orator as Brutus is') is one of the rhetorician's weapons: and I suspect that everything which seems to fall by chance from Latimer's lips is consciously devised to hold the attention and undermine the resistance of the audience. He establishes intimacy with them in order to sway them. It is a well understood homiletic technique which descends to him from the Middle Ages (his method has affinities with that of Chaucer's Pardoner) and which has survived into our own days under the opprobrious names of 'straight talkism' or 'high pressure Christianity'.
Some cannot endure it. They have a right to their taste, but they must not infer from the style that Latimer is a charlatan. The spiritual cheapjack and the sincere preacher both have equal, though different, motives for wishing to arrest and control a congregation and therefore may both (if they can) adopt a manner which will certainly achieve this end. 'Young feller', said General Booth to Kipling, 'if I thought I could win one more soul to the Lord by playing the tambourine with my toes, I'd -- I'd learn how.' The only test which Latimer would admit as relevant for his sermons is their practical efficacy. And they were efficacious.
We are told that when he preached on the duty of restitution it was not long before certain anonymous donations began to reach the king's treasury. That does not perhaps justify us in calling his work literature: but the mere strength and pith and urgency of his sentences, in that age so given to verbiage, is a literary virtue. He is as importunate as Hazlitt. He would have been a fine broadcaster." (p. 192-194)
Now try reading his sermon on the Armor of God. I have to say, I love his informal style, it runs better than much 16th century writing, as I know that's the way he preached.
